- the arithmetic circuit 150 calculates and obtains a maximum value of differences between pieces of arm orientation data at two different timings as an arm-swing angle for one cycle. Then, the arithmetic circuit 150 stores the obtained data regarding the arm-swing angle in a predetermined storage area of the memory section 160 .

- the user US By the exercise data stored in the information communication device 300 being displayed on the display section 330 , the user US provides the arm-swing angle included in the exercise data with evaluation information indicating whether or not the condition is desirable, and the resultant data is stored as evaluation data in the memory 350 .
- the evaluation data stored in the memory section 350 of the information communication device 300 is read out, transmitted via the communication circuit section 310 to the terminal 100 or 200 , and stored in the memory section 160 or 250 .
- exercise data including an arm-swing angle obtained by the terminal 100 or 200 is compared based on the evaluation data transmitted from the information communication device 300 . Then, based on the comparison result, the user US is notified of exercise motion information and the exercise support information.
- evaluation processing for providing exercise data with evaluation information indicating whether or not the condition is desirable may be performed with the exercise data stored in the memory section 350 of the information communication device 300 being displayed on the display section 140 , 141 , or 231 of the terminal 100 or 200 connected via wired or wireless communication, and evaluation data after the provision of the evaluation information may be stored in the memory section 350 of the information communication device 300 .
- the user US uses the terminal 100 or 200 and the information communication device 300 to access the network server 500 via the network 400 and, with the exercise data stored in the memory section 550 being displayed on the display section 140 , 141 , or 231 of the terminal 100 or 200 and the display section 330 of the information communication device 300 , provides evaluation information indicating whether or not the condition is desirable to an arm-swing angle included in the exercise data. Then, the resultant data is stored in the memory section 550 as evaluation data.
- the evaluation data stored in the memory section 550 of the network server 500 is read out, transmitted directly via the network 400 or via the network 400 and the information communication device 300 to the terminal 100 or 200 , and stored in the memory section 160 and 250 .
- exercise data including an arm-swing angle obtained by the terminal 100 or 200 is compared based on the evaluation data transmitted from the network server 500 . Then, based on the comparison result, the user US is notified of exercise motion information and the exercise support information.
- the degree of arm swing during the motion of an exercise such as a running exercise can be accurately ascertained and judged, as in the case of the above-described first and second embodiments. Accordingly, an exercise motion status including an arm-swing angle can be suitably transmitted to the user, and exercise support for guiding the user to an appropriate exercise motion status can be performed.
- exercise data obtained by the terminal worn on a human body can be transmitted as appropriate to the information communication device and the network server and stored in the memory section, and processing for providing evaluation information to the exercise data can be performed on the information communication device and the network server. Therefore, the terminal to be worn on a human body can be achieved with a device structure having a relatively small storage capacity (memory) and a simple arithmetic processing function.
- the method is described in which evaluation information indicating whether or not the condition is desirable is provided to an obtained arm-swing angle in the arm-swing evaluation processing by the user US and a comparison with the current arm-swing angle is performed based on the arm-swing angle provided with the evaluation information in the arm-swing status judgment/support processing.
- the present invention is not limited thereto.
- information regarding a footstep count and pitch calculated based on sensor data may be included as an element when evaluation information is provided and a comparison and judgment are made, in addition to the arm-swing angle.
- the terminals 100 and 200 constituting the exercise support device are worn on an upper arm portion and a forearm portion of a human body. Then, based on acceleration data detected by the terminals 100 and 200 , a judgment is made as to the exercise motion status of the user (whether or not the user is running, walking, etc.), and one cycle (a period corresponding to one footstep) in the operation of detecting the arm-swing status (arm orientation) is set.
- the present invention is not limited thereto.
- a terminal having an acceleration sensor incorporated therein may be worn on the trunk of a human body such as a chest or hip portion to obtain the acceleration data described above.
